Abstract
PURPOSE: To improve the safety and the reliablity of a reactor by the prevention of air admixture, by means of using stop cheque valves as stop valves of branched pipings connected to an absorbing piping in a core cooling device for emergency.
CONSTITUTION: An absorbing piping 4 is connected from a plenum chamber 1 up to a pump for injecting 2, and the branched pipings of a manometer 7 and a sealing water pump 6 are set up at the piping 4. Stop cheque valves are set up as stop valves 8, 9 at the branched pipings. If a loss of coolant accident may be generated in the reactor, a separating valve 10 is opened, and the pump for injecting 2 is started. At this time, the sealing water pump 6 is stopped, but the stop valves remain opened. When a accident is generated, it is necessary to be operated during 3W6 months of a long term, and when a time to absorb the air from the failed position may come during the long term, due to the failure of the pipings of the sealing water pump 6 or the manometer 7 in the downstream of the stop valves 8, 9, the stop valves 8, 9 prevent the entrance of the air
